A creature ran across my driveway

I own 14 acres of woods and am surrounded by many more. I was driving down my driveway when a bipedal creature about 4 ft tall and about as wide as my thigh (I'm 5'6" 140lbs so not big) ran out of the woods to my left, across my driveway and into the woods/yard of the property on the right. It was about 10 yards away. It looked like a tree on legs with small arms. No visible curves, hips or shoulders. Just straight. It was brown, skinny, no fur or hair, lightning fast and light as a feather. Almost looked like it wasn't even touching the ground. Didn't hear a sound from it running and all the birds and other animals were dead silent. When it ran it didn't prance like most animals or run like a human. It's legs were moving as if you were pedaling a bicycle. I saw the back and a bit of the right side of it. I didn't see the front or a face. I didn't see a tail, ears or any other body parts a normal animal or human would have. About 2 months ago I was outside around 10pm and there were 2 owls hooting back and forth. Then I heard this God awful screeching sound (wasn't a fisher cat or screech owl). I have no idea if that was related or not. I don't do drugs and I was not drinking. I am not on any medication or anything like that. I don't know if it was for sure an alien but I don't know what else it could be. I did not see any craft or anything although I wasn't going to walk thru the woods to look either.
